why when u spin alot you gonna puke?

Answer 1

A sack of fluid inside the ear acts as balance organ for us. When you spin a lot, there creates a turmoil in that liquid and you get the sensation of reeling. That reeling causes nausea and vomiting.

Although earth spins a lot, it is not a "Earth Science and Geology" category of questions. Try putting this question in health and see the view of some physicians.
